Ko te Tangohanga Wāhanga Mārō (SPE) he tauira hangarau i mua i te maimoatanga i whakawhanakehia mai i te waenganui o te 1980s.Ka whakawhanakehia e te whakakotahitanga o te tangohanga wai-totoka me te chromatography wai.Ka whakamahia te nuinga mo te wehenga, te purenga me te whakarangatira i nga tauira.Ko te kaupapa matua ko te whakaiti i te wawaotanga matrix tauira me te whakapai ake i te arokitenga.

I runga i te ariā o te chromatography wai-totoka, ka whakamahia e te hangarau SPE te whakaurunga whiriwhiringa me te elution whiriwhiri hei whakarangatira, wehe me te pure i nga tauira.He tukanga tango tinana tae atu ki nga wahanga wai me te totoka;ka taea hoki te whakatau tata ma te kii he mahinga chromatographic ngawari.
Hoahoa hoahoa o te taputapu tangohanga wahanga totoka
Ko te SPE te maataapono wehewehe o te chromatography wai ma te whakamahi i te whakaurunga whiriwhiri me te elution whiriwhiri.Ko te tikanga e whakamahia nuitia ana ko te tuku i te wairewa tauira wai i roto i te adsorbent, te pupuri i te matū kia whakamatauria, katahi ka whakamahi i te whakarewa o te kaha e tika ana hei horoi i nga poke, katahi ka tere te whakakore i te matū hei whakamatautau me te iti o te whakarewa, kia rite ki te whakatutuki i te kaupapa o te wehenga tere, purenga me te kukū.Ka taea hoki te whakakopa i nga poke pokanoa me te tuku i te matū kua ine kia rere ki waho;ki te whakauru i nga poke me te matū ine i te wa ano, ka whakamahi i te whakarewa pai hei whakaemi i te matū ine.
Ko te tangohanga o te tikanga tangohanga totoka he totoka, a ko tana kaupapa mahi i runga i te meka ko nga waahanga hei ine me nga waahanga pokanoa e noho tahi ana i roto i te tauira wai he rereke nga kaha ki runga i te kaihoko tangohanga totoka, kia kua wehea tetahi ki tetahi.Ko te kaihoko tangohanga wahanga totoka he whakakii motuhake kei roto C18, C8 ranei, nitrile, amino me etahi atu roopu.
